Abstract

The Tawang-Chu River Basin of the eastern Himalayas is a heterogenous region that is highly vulnerable to climate change. The changing temperature patterns in this mountain river basin play a vital role in changing the ecological system and inter-ecological nexus. Landsat satellite images were used to analyze spatio-temporal changes in Land Use and Land Cover (LULC) patterns in the basin. The changing trends of Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) were analyzed (at intervals of five years) using Landsat data. Changes in rainfall trends were analyzed using the Mann-Kendall test. The results show that fluctuations in annual temperature and increasing rainfall uncertainties are affecting LULC vegetation health.
